The Karaganda region includes the Nura-Sarysu, Balkhash-Alakol, Ishim, Irtysh and Tobol-Torgai river basins.
There are 599 water bodies in the region, including 107 rivers, 83 lakes, 409 artificial reservoirs, dams with hydraulic structures. The rivers belong to the basins of the inland lakes Tengiz, Karasor, Balkhash and the Irtysh River. The density of the river network decreases from north to south, depending on the topography. 11 rivers have a length of over 100 km.: Nura - 978, Torgay - 827, Sarysu - 800, Shiderty - 502, Uly – Zhylanshyk - 422, Kulanotpes - 364, Kalmakkyrgan - 325, Tuyndyk - 303, Tokyraun - 298, Zharly - 193 Taldy - 129.
In the southeast, the region includes part of the coast of Lake Balkhash, the third largest reservoir in Kazakhstan.
To the north of Karkaralinsk is a hilly closed plain - Karasor. Within its limits, there are about 50 lakes (Karasor, Saumalkol, Balyktykol, etc.). The depth of the water bodies is on average 1 m, in places up to 4-5 m. Black hydrogen sulfide mud with healing properties and medical use lies at the bottom.
The largest lakes of the region: Balkhash - 18.2 thousand square meters. km, Karasor - 154 sq. km. km, Kypshak - 64.7 square meters. km, Kerey - 62.8 square meters. km, Karakoyyn - 72.5 square meters. km, Kiyakty - 51.6 square meters. km, Shoshkakol - 32.0 sq. km, Balyktykol - 25.8 sq. km.
An important role in the balance of the region’s water supply is played by reservoirs and canals: Samarkand (on the Nura river), Cherubainurinsk (on the Cherubainura river), Kengirskoye (on the Kengir river), Zhezdinskoye (on the Zhezdy river), as well as dozens of small ponds on small watercourses.
Since 1973, the Irtysh – Karaganda canal has been operating in the region - a large hydraulic structure with a length of 458 km, providing drinking water in the cities of Karaganda and Temirtau. The water supply from the canal averages 75 cubic meters. meters per second. The channel is unique in that water is supplied from a lower height (relative to sea level) to a higher one, for which about 20 pumping stations are involved.
